The deal marks the second time in less than a month that Amazon has bulked up its children’s programming. Earlier this month, the Seattle company announced a deal with Viacom to pick up “SpongeBob SquarePants,” “The Backyardigans,” “Dora the Explorer” and many other shows Netflix lost when it declined to renew its own deal with the Hollywood studio, which owns Nickelodeon.

Netflix officials have described their decisions to not renew agreements with Viacom and other companies as intentional, saying that the Internet video company is focusing on exclusive content. But such decisions have roiled many users.

Amazon offers some 41,000 streaming movies and TV episodes at no extra charge to Amazon Prime subscribers. The company charges $79 a year for that service, which also provides subscribers with two-day shipping on most of their orders at no extra charge and allows them to borrow one e-book a month from the company’s Kindle store.

Amazon’s streaming service offers more than just kids’ fare. Thanks to the new deal with PBS, for example, the company will also offer additional episodes of “NOVA” and “Masterpiece” and some additional documentaries by Ken Burns.

The companies did not disclose the terms of the agreement, saying only that it was a multi-year deal.
